[0002] Metal materials such as high-temperature alloys, titanium alloys, and high-strength steel are essential key structural materials for aviation, aerospace, energy, nuclear industry, petrochemicals, national defense weaponry, and national economic development. Because metal materials are subjected to high temperatures, high pressures, and stresses for extended periods of time, controlling the microstructure of metal components during vacuum heat treatment is particularly important.

[0003] Large vacuum heat treatment equipment has a large furnace chamber. After running for a period of time, the aging of components or poor contact of heating elements will lead to uneven temperatures at different locations in the furnace, affecting the heat treatment quality of the product. Therefore, regular inspection and adjustment are required. Utility Model Content

[0007] As mentioned above, a return spring is fixedly connected to the side of the hydraulic cylinder, and one end of the return spring away from the side of the hydraulic cylinder is fixedly connected to the circumferential surface of the force-bearing rod. The function of the return spring being fixedly connected to the circumferential surface of the force-bearing rod at one end away from the side of the hydraulic cylinder is that when the temperature measurement is completed, the force-bearing rod is reset by the elasticity of the return spring and thus released.

[0008] As mentioned above, the number of the hydraulic cylinders and the return springs is set to nine, and they are distributed on the outer surface of the frame. The number of the hydraulic cylinders and the return springs is set to nine, and they are distributed on the outer surface of the frame.

[0009] As mentioned above, a lifting mechanism is provided on the top of the frame, and the lifting mechanism includes a motor, the bottom of the motor is fixedly connected to the top of the frame, the output shaft of the motor is fixedly connected to a threaded rod, the circumferential surface of the threaded rod is threadedly connected to a threaded sleeve, the top of the threaded sleeve is rotatably connected to a connecting rod, and the top of the connecting rod is rotatably connected to a lifting plate, the top of the frame is fixedly connected to a telescopic column, the telescopic end of the telescopic column is fixedly connected to the bottom of the lifting plate, and the lifting mechanism is provided on the top of the frame to transport the frame through the lifting mechanism after the installation of the fixing mechanism is completed.

[0010] As mentioned above, the bottom of the frame is provided with moving wheels, and the side of the frame is fixedly connected with a handle, and the frame on the frame is transported to the inside of the furnace through the moving wheels and the handle.

[0011] As mentioned above, the circumferential surface of the threaded rod is fixedly passed through the limiting plate, and the side of the motor is fixedly connected to a limiting shaft. The circumferential surface of the limiting shaft passes through the side of the threaded sleeve and is slidingly connected to the side of the threaded sleeve.

The purpose of the telescopic columns and the moving wheels is to ensure the stability of the frame during the lifting process through the four telescopic columns.

[0013] Compared with the existing technology, this vacuum heat treatment furnace temperature measurement stabilization frame has the following beneficial effects:

[0014] 1. The utility model cooperates with each other through the components of the fixing mechanism, such as the hydraulic cylinder, the clamping plate and the reset spring. When the furnace inside the large vacuum heat treatment equipment has been running for a long time, the temperature at various positions in the furnace will be uneven due to aging of components or poor contact of the heating elements. At this time, the staff selects nine points on the stainless steel frame according to the size of the furnace and installs nine hydraulic cylinders at these points. At this time, the vacuum furnace needs to measure the temperature and nine thermocouples are placed in the nine hydraulic cylinders to fix the thermocouples.

At this time, the staff adjusts the frame to a suitable position according to the position of the furnace chamber of the vacuum heat treatment equipment, and then transports the frame to the entrance of the furnace chamber through the moving wheels and handles, so that the frame enters the interior of the furnace chamber. This design achieves the effect of lifting the frame and effectively reduces the labor generated by manually carrying the frame.

The purpose of the fixed connection between the end of the return spring 35 away from the side of the hydraulic cylinder 31 and the circumferential surface of the force-bearing rod 32 is that when the temperature measurement is completed, the force-bearing rod 32 is reset by the elasticity of the return spring 35 and thus released.

[0028] The number of hydraulic cylinders 31 and return springs 35 is set to nine, and they are distributed on the outer surface of the frame 2. The number of hydraulic cylinders 31 and return springs 35 is set to nine, and they are distributed on the outer surface of the frame 2. The function is to realize the nine-point temperature measuring device method through nine hydraulic cylinders 31.

[0029] When the furnace inside a large vacuum heat treatment equipment has been running for a long time, the temperature at various positions in the furnace will be uneven due to aging of components or poor contact of heating elements. At this time, the staff selects nine points on the stainless steel frame 2 according to the size of the furnace and installs nine hydraulic cylinders 31 at these points. At this time, the vacuum furnace needs to measure the temperature, and nine thermocouples are placed inside the nine hydraulic cylinders 31 respectively.

At the same time, the hydraulic rod 33 of the hydraulic cylinder 31 is extended outward by the pressure of the liquid inside the hydraulic cylinder 31. The extension of the hydraulic rod 33 drives the splint 34 to extend outward to fix the thermocouple. When the temperature measurement is completed, the force-bearing rod 32 is reset by the elasticity of the reset spring 35, thereby releasing the fixation of the thermocouple.

[0030] A lifting mechanism 4 is provided at the top of the frame 1. The lifting mechanism 4 includes a motor 41. The bottom of the motor 41 is fixedly connected to the top of the frame 1.

The circumferential surface of the limiting shaft 410 passes through the side of the threaded sleeve 43 and is slidingly connected to the side of the threaded sleeve 43 to prevent the threaded sleeve 43 from rotating during the movement through the limiting shaft 410.

[0033] The number of telescopic columns 46 and moving wheels 47 is set to four, and they are symmetrical with each other along the vertical center axis of the frame 1. The purpose of setting the number of telescopic columns 46 and moving wheels 47 to four, and they are symmetrical with each other along the vertical center axis of the frame 1 is to ensure the stability of the frame 2 during the lifting process through the four telescopic columns 46.

[0034] When the thermocouple is fixed, the frame 2 needs to be placed in the furnace. At this time, the staff starts the motor 41, and the output shaft of the motor 41 rotates counterclockwise.

The threaded sleeve 43 moves from left to right, driving the connecting rod 44 to move from left to right. The connecting rod 44 moves from left to right, driving the lifting plate 45 to move upward through the telescopic column 46. At this time, the staff adjusts the frame 2 to a suitable position through the position of the furnace chamber of the vacuum heat treatment equipment, and then transports the frame 2 to the entrance of the furnace chamber through the moving wheel 47 and the handle 48, so that the frame 2 enters the interior of the furnace chamber.
